Volatile organic compound emissions from painting operations are of primary concem in the automotive industry and require costly control measures using vapor-phase activated-carbon adsorption. At Ford Research Laboratory, Dearborn, Michigan, a process modification has been proposed as a supplemental or an alternative control measure to convert an existing paint-sludge pit, part of a spray-booth...

The kinetics of dissimilatory reduction of goethite (alpha-FeOOH) was studied in batch cultures of a groundwater bacterium, Shewanella putrefaciens, strain CN32 in pH 7 bicarbonate buffer. The rate and extent of goethite reduction were measured as a function of electron acceptor (goethite) and donor (lactate) concentrations. Increasing goethite concentrations increased both the rate and extent ...

The Monod model is a classical microbiological model much used in microbiology, for example to evaluate biodegradation processes. The model describes microbial growth kinetics in batch culture experiments using three parameters: the maximal specific growth rate, the saturation constant and the yield coefficient. However, identification of these parameter values from experimental data is a chall...

This paper proposes an uncertainty set update method for a class of discretetime nonlinearly parameterized systems. The method is based on the sequential application of a method proposed for linearly parameterized uncertain nonlinear systems in which the nonlinearly parameterized systems can be treated as linearly parameterized uncertain systems at each step. It is demonstrated that, given a pe...

Municipal wastewater consists of a large fraction particulate organic matter. During biological treatment these particles undergo extracellular depolymerisation before products are taken up by bacteria (MW < 0.6 kDa). Particle degradation and intermediate formation dynamics is important in process analysis as the transport regime differ. This work aims to develop model for particle that incl...

This paper describes a modeling effort demonstrating that dimensionless groupings of classical process parameters can be used to predicting process dynamics of batch simultaneous saccharification and fermentation (SSF) processes. Michaelis–Menten enzyme kinetics and Monod growth kinetics were employed, and inhibition of enzyme action and inhibition of microbial growth were neglected. The SSF pr...

AIMS The possibility of substrate inhibition by glucose on biomass and pediocin production was studied in cultures of Pediococcus acidilactici on a residual medium. METHODS AND RESULTS Calculation of the substrate inhibition coefficient in the context of microbial growth is generally laborious, and very prone to experimental error. However, a simulation combining logistic and Monod kinetics e...
